This is the problem in steps the final output is at the bottom.

Program: Data visualization (Java)

(1) Prompt the user for a title for data. Output the title.

Ex: Enter a title for the data: Number of Novels Authored You entered: Number of Novels Authored

(2) Prompt the user for the headers of two columns of a table. Output the column headers.

Ex: Enter the column 1 header: Author name You entered: Author name Enter the column 2 header: Number of novels You entered: Number of novels

(3) Prompt the user for data points. Data points must be in this format: string, int. Store the information before the comma into a string variable and the information after the comma into an integer. The user will enter -1 when they have finished entering data points. Output the data points.

Store the string components of the data points in an ArrayList of strings. Store the integer components of the data points in a second ArrayList of integers.

Ex:

Enter a data point (-1 to stop input): Jane Austen, 6 Data string: Jane Austen Data integer: 6

(4) Perform error checking for the data point entries. If any of the following errors occurs, output the appropriate error message and prompt again for a valid data point.

If entry has no comma

Output: Error: No comma in string.

If entry has more than one comma

Output: Error: Too many commas in input.

If entry after the comma is not an integer

Output: Error: Comma not followed by an integer.

Ex:

Enter a data point (-1 to stop input): Ernest Hemingway 9 Error: No comma in string. Enter a data point (-1 to stop input): Ernest, Hemingway, 9 Error: Too many commas in input. Enter a data point (-1 to stop input): Ernest Hemingway, nine Error: Comma not followed by an integer. Enter a data point (-1 to stop input): Ernest Hemingway, 9 Data string: Ernest Hemingway Data integer: 9

(5) Output the information in a formatted table. The title is right justified with a minimum of 33 characters. Column 1 is left justified with a minimum of 20 characters. Column 2 is right justified with a minimum of 23 characters.

Ex:

Number of Novels Authored Author name | Number of novels -------------------------------------------- Jane Austen | 6 Charles Dickens | 20 Ernest Hemingway | 9 Jack Kerouac | 22 F. Scott Fitzgerald | 8 Mary Shelley | 7 Charlotte Bronte | 5 Mark Twain | 11 Agatha Christie | 73 Ian Flemming | 14 J.K. Rowling | 14 Stephen King | 54 Oscar Wilde | 1

(6) Output the information as a formatted histogram. Each name is right justified with a minimum of 20 characters.

Ex:

Jane Austen ****** Charles Dickens ******************** Ernest Hemingway ********* Jack Kerouac ********************** F. Scott Fitzgerald ******** Mary Shelley ******* Charlotte Bronte ***** Mark Twain *********** Agatha Christie ************************************************************************* Ian Flemming ************** J.K. Rowling ************** Stephen King ****************************************************** Oscar Wilde *
This is the preloaded code:

import java.util.Scanner;
import java.util.ArrayList;

public class DataVisualizer {
public static void main(String[] args) {
/* Type your code here. */

return;
}
}

This is in a Java learnig program not an Java IDE. This question has been answered on Transtutors before but that code doesn't work, I has multiple errors acourding to the learning program. can someone please help me out with this. Thank you.

The code needs to output exactly as it shows above or it is considered incorrect.
